  • Patent number: 12148438
    Abstract: An encoding apparatus and a decoding apparatus in a transform between a Modified Discrete Cosine Transform (MDCT)-based coder and a different coder are provided. The encoding apparatus may encode additional information to restore an input signal encoded according to the MDCT-based coding scheme, when switching occurs between the MDCT-based coder and the different coder. Accordingly, an unnecessary bitstream may be prevented from being generated, and minimum additional information may be encoded.

  • Publication number: 20240264091
    Abstract: Provided is a method for inspecting whether the shape and the depth of a via hole formed in a wafer are defective. The method includes a process of receiving three-dimensional image information of the via hole formed in the wafer, a process of detecting an edge of the via hole by using the received three-dimensional image information and an edge detection algorithm, a process of determining whether the detected edge is within a set range, thereby determining whether the shape of the via hole is defective, a process of dividing a three-dimensional image of the via hole generated from the three-dimensional image information of the via hole into at least two regions when the detected edge is within the set range, and a process of determining whether a volume of each divided region is within a set range, thereby determining whether the depth of the via hole is defective.
